Most pricing for pressure washing is done either based on linear footage or square footage multiplied by a price per linear or square foot.  You can also charge based on an hourly rate.  The prices below are just estimates based on national averages.  Prices in your area may differ.  Many companies charge flat rates for certain jobs such as house cleaning.  We also have a spreadsheet program available here that will help you to price jobs.

Houses

1. $90 – $275 flat price
2. $.75 – $1.25 per linear foot for a single story house.
3. $1.75 – $2.25 per linear foot for a two story house.

Gutters

This basically involves blowing out leaves and dirt from a gutter system.  Having the right equipment will make this type of work much easier.

1. $100 for a single story
2. $135 for two floors
3. $200 for three floors.

Specialty gutters such as wooden ones will be priced a little higher.

Boats

Bottom only – $5 per linear foot.
Entire boat – $10 per linear foot.

Roofs

When pricing a roof cleaning job you will need to figure the square footage.  To do this take the sum of the length time’s the width then multiply it by 1.35. This will give you a close estimate of the square footage.

For a typical 2000 square foot roof you would charge about .20 cents per square foot which would be $400.   If the roof has a high pitch you can double or triple the charge or just pass on the job.  Safety is always number one.  The chemicals you will need will cost you around $50 so make sure to keep this in mind when pricing.  With basic equipment it will take approximately 5 hours to treat and rinse off the roof.  If you have the proper equipment you can do the same job in about 3 hours.  You can see how your per hour profit can differ depending on what equipment you have.

Driveways & Sidewalks

1. $60 – $150 flat price depending on size
   
2. $.08 – $.14 per square foot.
   

Fences, Decks and Siding Jobs

Pricing fence, decks and siding is calculated by the square foot just like a roof.  Take the square footage of the fence, deck or siding and multiply by .20 – .25 cents.  You will use chemicals on this type of job also but you will be able to finish in much less time.
Mobile Homes

1. Single Wide Mobile Home – $50 – $85 depending on condition.
2. Double Wide – $80 – $100 also depending on condition.

Commercial Type Cleaning

1. Basic Surface cleaning – $.08 – .12 cents per square foot.
2. Dumpsters – $75 for Standard and $150 for Large

Parking Lots, Sidewalks & Drive-Thru’s

1. Parking Lots, Garage Floors – $.05 – $.25 per square foot depending on condition.
2. Parking Spaces – $10 – $20 each (bank space would be less than a convenience store space.

As a backup you can price any job using the following basic formula.

Double your materials cost and then charge $45 – $50 for cold water or $55 – $60 for hot water cleaning.  The key is to pre estimate the time it will take to do the job.  Customers normally want to know ahead of time what they will be charged so pre estimating the job will put them at ease.  For large commercial jobs you can just set a rate and keep track of your time and charge the customer either when you are done or as you go.  In this case you would not pre estimate time and a commercial customer would be fine with that.
